DENTAL MDICINE-RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 732,662, dated June 30,1903.

Application fila December 19, 1901. Serial No. 86.594. (No model:)

To all whom it may concern- Be it known thatI', GEORGE B. SMITH, acitizen of the United States, and a resident of Fremont, in thecountyofSanduskyand State of Ohio, have invented certain new and usefulImprovements in Dental Medicine-Receptacles, of which the following is aSpecification.

The purpose of this invention is to provide a rockable and self-rightingbottle for dentists use which reduces thelossof medicine frontevaporation and accident to a minimum while the bottle is still open andready for use by the operator.

In general terms said invention embraces a divided rockable andself-righting bottle 1, acap or cover 2, and a gro'und or othertightfitting stopper 3.

Referring nowto the drawings of my invention, Figure 1 represents thesame in perspective view, a portion of the cap or cover being cut awayto show other parts. Fig. 2 represents a cross-section of the bottle onthe line A A of Fig. 1. Fig. 3 represents a crosssection of the bottleon the line B B of Fig. 1. Fig. 4 represents a longitudinal section ofthe stopper on its median line. Fig. 5 represents the cap or cover.

It is well known that dentists in the practice of their profession usemany kinds of medicines which are more or less volatile and have to beapplied by means of cotton or some other light absorbent and still otherkinds, such as acids, which have lto be applied by meansof a suitablewire or broach, all of which un'der the present practice is furnishedin'ordinary bottles, which to prevent evaporation or accidental spillingvare required to bo closed after each time they are used. In Opening andclosing these bottles and to obtain the required amount of medicine bothhands are frequently required, and that, too, at a time when from thenature of t the Operation it is least convenient to use them for thatpurpose. and hence much in-t I obviate these incon-' convenienceresults. veniences by means of my invention.

The bottle is made rockable in form, as represented in Fig. 2, and isdivided into two receptacles 1b by means of a raised bridge 1, overwhich the medicine is made to fiow as the bottle is rocked in theprocess of using. It is provided with a neck 1, as in the case ofordinary bottles, and to which the capor cover is ground to fit.

The stopper 3 is formed with a conical or funnel-shaped passageextendingin line with it's`axis, as seen in Fig. 4, the open month beingat its external end. The province of this month is to receive a ball orwad of cotton held by pliers or tweezers in the hand of the operator,and its capacity is accordingly. Said stopper should he adapted so thatwhen in place its inner end will nearly touch the bridge 1, as shown indotted Outline in Fig. 3. The inner end of said passage 3:L is socontracted as to prevent most of the cotton from being forced throughsaid passage and into the bottle, while at the same time it permits someof the fibei-sto come in contact With and absorb some of'the medicine asthe bottle is rocked and the same is made to pass over the bridge andfrom o'ne receptacle to the other. Said passage is also intended toaccommodate the use of a suitable wire or broach-wonnd with cotton, asdentists frequently use the same in applying medicine to thenerve-canals, said wire or broach with cotton wound thereon being passedthrough said passage and into the bottle, and its capacity or dimensionsare accordingly. Ordinarily the medicine will not rise within thispassag'e; but it may be made to rise therein by any undue rocking of thebottle; but in such cases the cotton serves to arrest the flow. Asobserved in Fig. 3, I make the bridge lowest at its middle, and thusfacilitate the use of the bottle as long as there is any medicineremaining in either receptacle. It Will therefore be observed that bymeans of said contracted passage through the stopper not only is allloss of medicine due to evaporation or accidental spiiling reduced to aminimum, but at the same time the bottle is left open and ready for use,as required. i

The neck 1? is not made longer'than-necessary to receive the caporcover, andl thus by preventing the bottle from becoming topheavy I aidin making the same self-righting.V

The bottle is made self-rightingwithin reasonable limits of use by meansof its form, as represented in Fig. 2, the bottle When rocke'd having asurplus of weight between its bottom and a vertical line drawn from thepoint of contact.

It is manifest that the bottle might be filled through the passage inthe stopper; but the necessities of practical construction require alarge month through which to reach and form the two receptacles and givesuitable shape to the bridge.

The flange 3b forms no feature of my invention, but is convenient as ameans of holding While grinding.

VVhile these bottles may be made from other material, yet for manifestreasons I prefer to make them of glass.

Having described my invention, I now claim as new-- A rockable bottlefox-med with two receptacles or chambers divided by a bridge over whichits contents is made to flow in passing from one receptacle to theother, in combination With a stopper having a conical or funnel-shapedpassage in line with its axis, the smaller'or rednced radins of saidpassage be,- ing at its inner end, so adapted that when in place theinner end of said stopper is in close proximity with the medicine as thesame is made to pass over said bridge.

In testimony whereof I have signed my name to the foregoingspecification in the presence of two witnesses.

GEORGE B. SMITH.
